The answer is B.
This is because the triangle is an isosceles triangle, meaning that the answer to 4x-8 = x+4
You can rearrange this question to put the x’s on both sides and the integers on both sides so that 4x-x = 4 + 8. This cancels down to 3x = 12. To find x, divide 12 by 3, which is 4.
To check this answer, you can input 4 into both of the equations. (4 x 4) - 8 = 8, and 4 + 4 is also 8. Hence, you know x = 4.
Another, more time-consuming way of doing this question would be to simply input each possible value (A, B, C and D) into both equations until the both equations came out with the same number.
Hope this helped :)
Answer:
c. Eolian
Explanation:
By observing the environment presented in the question above, we can identify the presence of many sand sheets and different types of dunes. These characteristics are directly related to Eolian Environments, which are those where the wind is the main means of transporting sediment and presents a predominance of sand, like the environment presented in the question. These environments are usually drier and have a low concentration of water.
